I am new to solidworks, came from inventor. a co worker already had a part built so we could edit to the proper specs in inventor, but now we need to learn how to create this part in solidworks. helical spoilers (strakes) for a smoke stack.  i know there is a helical option in solidworks and youtube videos try to help me but cant figure anything out.  i found one solidwork part that also helps me but i cant figure it out. i have attached it and an image of what i need.
